Scientists almost every month to remind us about the dangers of global warming, saying that a gradual increase in the Earth’s temperature could lead to reduction of reserves of drinking water, extinction of animals and other terrible consequences. Many of us all this panic about climate change is still not clear, because in Russia, as a rule, hot weather is replaced by cold and it is considered normal. Yes, and if the temperature will rise a couple of degrees — what’s the worst that can happen? Yes, the effects of global warming we may not notice, but they are clearly visible in Australia, because there is a mass killing algae and fish.
The gradual increase of the average temperature of the Earth leads to the increase in the number of droughts and floods. Of course, all these weather phenomena have a great impact on plant life and animal life. Damaged during droughts and floods, plants and other living organisms trying to recover, but this requires a lot of time. Most likely, they will not be able to go back to their original, healthy state because of disastrous weather phenomena occur more often.
The effects of global warming
According to scientists, due to global warming weather events have affected about 45% of the coastal area of Australia. In the period from 2011 to 2017 excessively dry weather caused damage to growing close to the shores of the coral and the algae. But they are shelter and food for many aquatic life — deprived of all this, many fish, turtles and crustaceans simply began to die.

One of the most severe blows on the coastline of Australia occurred in 2011, when the average temperature in this region increased by 4 degrees Celsius. Even this difference in temperature was the reason that for more than 1,000 kilometers biologists began to notice bleached coral reefs. It is known that the loss of color of corals means to stop their growth and destruction. Thus, due to global warming its natural habitat lost many fish, sponges and sea turtles.
Healthy and dead sea grass
Bleached corals were seen in 2013, 2016 and 2017. Damage also received a so-called Great barrier reef that stretches along the coast of Australia by as much as 2,500 kilometers and visible even from space. It was also noted that extreme natural events have destroyed mangrove forestslocated in the Northern part of Australia.

Damaged coral reefs and forest are trying to recover, but it may take more than 15 years. If we talk about the recovery of populations of some species of aquatic creatures, such as sharks, the recovery may take more than 60 years. To provide the nature and comfortable conditions, to humanity, it is important to reduce greenhouse gas emissions.

Heat wave in Europe
Still don’t believe in the danger of global warming? Take a look at the headlines of news publications, which at the end of July and talking about abnormally high temperatures in European countries. Since 25 July, in Germany, the temperatures rise up to 40 degrees Celsius. The same high temperature observed in the Netherlands, Belgium and France.
Record hot weather from space. The brighter red the color, the higher the temperature
At abnormally high temperature already have serious consequences. For example, the authorities of France and Germany had to temporarily stop the operation of nuclear power plants what people come up fairly large bills for the light. Without a partial closure it was impossible to do because the river is heated so that their water could not cool the nuclear reactors.
I think people already have to move to Siberia?
The reason for the abnormally high temperatures is the formation of areas of high pressure over Greenland and North-Central Europe. Because of them, the mass of air that would cool the air, can’t get in the European countries. At the moment the country affects only the hot air coming from the deserts.
